Lake Tiorati was formed by clearing swampland in Harriman State Park and constructing a concrete dam to make two ponds into one large lake. Surrounded by meadows and rolling, wooded hills, the park offers excellent swimming, fishing, boating and picnicking. In winter, if conditions allow, the lake is used for ice fishing. The pioneer campsites near the lake may be used by bonafide groups.

Scout camping is available.

Biking - Helmets required.

Fishing - NYS fishing license required.

Launch Site - Boat permit and key required.

Group camping is available.
